CAT 1R-1807 Advanced High Efficiency Oil Filter Pack of 2 — OEM fit, fine-particle filtration

If you need a direct-replacement oil filter from Caterpillar, this pair of 1R-1807 cartridges is engineered to match factory specifications for durability and filtration performance. These filters are designed for heavy-duty applications where contaminant control and oil cleanliness matter; always verify fitment in your engine's service manual before installation.

How does the CAT 1R-1807 improve oil protection?

The 1R-1807 uses media and construction tuned to trap wear particles and debris while maintaining proper oil flow. That balance helps reduce abrasive wear and keeps oil circulating efficiently under load.

• Advanced filter media captures fine particulates without choking flow
• Robust end-caps and gasket ensure a tight seal under pressure
• Built to Caterpillar dimensional and thread specifications for leak-free fit

What are the physical specifications and fit details?

Each filter in this two-pack follows CAT's specified dimensions and thread standard so it fits compatible housings. Check your equipment's parts list to confirm compatibility with the 1R-1807 thread and size.

• Thread: 1.125-16 UNF for direct installation
• Height: 262 mm and Diameter: 108 mm for correct sealing surface
• Sold as a quantity of two for simultaneous replacement or spare

How do I install and maintain these filters safely?

Installation follows standard oil-filter replacement steps: relieve system pressure, remove the old filter, clean the mounting surface, and tighten the new filter to the recommended torque/seating procedure. Dispose of used oil and filters following local regulations.

• Hand-tighten until gasket contacts, then follow torque or rotation guideline
• Replace filters during scheduled oil service intervals per engine manual
• Keep a spare from the two-pack on hand for quicker maintenance

Why choose genuine CAT filters instead of aftermarket alternatives?

Genuine Caterpillar filters are manufactured to match factory tolerances, material quality, and engineering expectations for equipment bearing the CAT name. Using OEM filters helps preserve designed clearances, flow rates, and protection levels that aftermarket parts may not guarantee.

• Manufactured to Caterpillar specifications for consistent performance
• Reduces risk of premature wear from poorly fitting or lower-quality media
• Simplifies parts sourcing when servicing CAT equipment

Who is this for: Operators, fleet managers, and maintenance technicians running Caterpillar or compatible heavy-duty engines who want a direct-fit, genuine CAT oil filter in a convenient two-pack. Choose this product if you prioritize OEM compatibility, reliable contaminant control, and keeping equipment service simple and predictable.
